When the American Registry for Internet Numbers (ARIN) was formed in
December 1997, it inherited the InterNIC database of existing IP
addresses and Autonomous System Numbers (ASNs). It also inherited the
responsibility to maintain the records in that database. These records
became known as "early registrations".
Discussions regarding early registrations took place among the Regional
Internet Registries (RIRs) and throughout their communities. These RIRs
comprised the Asia Pacific Network Information Centre (APNIC), the
American Registry for Internet Numbers (ARIN), the Latin American and
Caribbean Internet Addresses Registry (LACNIC) and the RIPE Network
Coordination Centre (RIPE NCC).
A decision was made that the interests of the holders of these early
registrations would be best served by managing the resources through the
RIR appropriate to the region in which they reside. The so-called ERX
Project was initiated to determine the RIR that should manage the
resources for each early registration.
This directory contains all completed early registration transfers that
took place during the ERX Project. This project ended in April 2005.
The lists in this directory still include those IP ranges that were
transfered by the RIPE NCC to other RIRs after 2005.
